Warts are skin growths caused by infection with the human papillomavirus (HPV). Most warts do not hurt unless they are in areas of the skin that are frequently irritated by rubbing or shaving, such as the foot, leg, or face.
The main types of warts include:
Treatment is not always necessary for warts. They can be treated if they are painful or unsightly, or because they are a type that is easily spread. If they are treated, home treatment with salicylic acid is often all that is necessary. If this does not work, prescription medicines or freezing (cryotherapy) can be tried. Surgery is also an option.
Genital warts can be spread during sex, so it is important to use latex condoms every time you have sex. Regular screening for cancer, including Pap smears for women, is also important.
